Automatic net paving device of anchor rod drill carriage for coal mine

Abstract

The invention discloses an automatic net paving device of an anchor rod drill carriage for a coal mine. The device comprises a rotating base, a lug base, a first arm, a first oil cylinder, a second arm, a second oil cylinder, a third arm, a third oil cylinder, a first spiral swing cylinder, a second spiral swing cylinder, a third spiral swing cylinder and a magnetic manipulator. The automatic net paving device of the anchor rod drill carriage for the coal mine realizes horizontal translation of the magnetic manipulator through the rotation of a worm wheel of the rotating base, realizes vertical translation of the magnetic manipulator through the telescopic motions of the first oil cylinder and the second oil cylinder, realizes front-back translation of the magnetic manipulator through the telescopic motion of the third oil cylinder, and realizes three degrees of rotating freedom of the magnetic manipulator through the rotation of the three spiral swing cylinders; and the magnetic manipulator realizes the grabbing and the pavement of reinforcement meshes, so that the automatic net paving device of the anchor rod drill carriage for the coal mine can realize automatic pavement of the reinforcement meshes so as to improve the paving efficiency of the reinforcement meshes.

Description

Technical field [0001] The invention relates to a component of a bolt drill carriage for coal mines, in particular to an automatic netting device of a bolt drill carriage for coal mines. Background technique [0002] In coal mining, when the coal seam is very thick, layer mining is adopted. That is, the coal seam is divided into several layers, generally two or three layers, and they are mined separately. In the process of stratified mining in coal mines, it is necessary to lay roof nets on the bottom of the working face during stoping, as the roof of the central mining area. After laying the roof net, when the next layer is mined, the falling gangue of the upper layer can be dragged, which is beneficial to the roof management during the mining of the lower layer. [0003] In the prior art, the netting equipment is generally completed manually by workers, which is low in efficiency. Summary of the invention [0004] The object of the present invention is to provide an automatic n...
